PRIMING-DEVICE ATTACHMENT.

Specification of Letters Patent. Patented Apr. 15, 1919.

Application filed. October 12, 1917,` Serial No. 196,141.

To all whom t may concern.' y

Be it known that I, LAURENCE E. FRENCH, a citizen of the United States,residing at Sebastopol, in the county of Sonoma and State of California,have invented certain new and useful Improvements in Priming- DeviceAttachments, of which the following is a specification. y

This invention relates to priming devices for internal combustionengines and it is the dominant object of the invention to provide apriming device having novel operating means whereby the cut-off meanstherefor can be actuated by foot or by hand for admitting the passage ofa priming Huid to the engine cylinders. i

Another and equally important object of the invention is to providemeans for allowing the cut-off means to be maintained in open positionsubsequent to the starting of the engine, thereby permitting thecylinders of the same to be brought to proper working temperatures.

Other independent objectsare to provide features of construction ofportions of the attachment which tend toward the attainment of the aboveaims irrespective of the relation in which they are used.

Other objects will be in part obvious and in part pointed outhereinafter.

The invention accordingly consists in the features of construction,combination of elements and arrangement of parts which will beexemplified in the construction herein-Y after set forth, and the scopeof the application of which will be indicated in the following claim.

In the accompanying drawing, wherein is shown one of various possibleembodiments of my invention I have illustrated a vertical sectionthrough a motor driven vehicle dashthe said straps carrying a fuel tanki therein. Connected to the fluid outlet port of the fuel tank 2 is aconduit 5, the free end of which extends to a point in proximity of thedashboard D. v

lSecured to the rear side of the dashboard D by means of bolts 6 is abracket 7 having a screw threaded opening formed therein for receiving acomplementally screw threaded portion of a rotary valve casing 8.Rotatably mounted in the casing 8 is a valve 9 having a lever 10 fixedlymounted on one extremity thereof and provided with a plurality ofopenings, the purpose of which will be subsequently apparent. A secondconduit 11 extends from the valve casing 8 into engagement with thecylinders of the internal combustion engine E.

.Passing vthrough a suitable slot or way formed in the lower portion ofthe dashboard D is a tubular casing member 12, this casing member beingsupported 4upon a plate 13 arranged over the said slot and secured tothe dashboard by means of screws 14 or other suitable fastening devices.A plunger rod 15 is slidably arranged in the tubular body 12 and has theinner end of the same pivotally connected to the lever 10 by means of asuitable connection passing through one of the openings formed therein,while the remaining end of the plunger rod is notched as at 16 andprovided with a head 17. Screw threaded guide caps 18 are turned intoengagement with complementally threaded portions formed on the tubularbody 12 and slidably receive the plunger rod 15 therethrough. As will benoted, the plunger rod 15 when moved inwardly to its full extent willhave the notch 16 formed therein engaged with the adjacent portion ofthe outer cap 18, thus, serving as means for maintaining the plunger rodin its innermost position against the tension of an expansible coilspring 19 arranged about a portion of the same within the tubular body12.

To permit operation of the cut-off means or valve from the front of themachine when cranking the same manually, a wire 20 or suitableconnection is passed through the remaining opening formed in the lever10 and extends through the mesh of the radiator construction of thevehicle to a point slightly beyond the same, whereupon it is looped tofacilitate engagement therewith.

It is to be noted, that thel fuel tank 4 ismounted above the level ofthe valve and as a. consequence, the flow of combustible fuel therefrominto the various cylinders of the engine E is permitted.

When operating the priming` device from the operators seat of thevehicle by foot, the head 17 of the plunger rod 16 is engaged by thefoot of user and moves inwardly against the tension of the spring untilthe notched portion 16 engages over the adjacent portion of the guidecap 18. Vhen in this position, the lever 10 will have been moved to fullopen position thereby admitting the passage of fuel from the tank 4 tothe cylinders of the engine E and effectively priming the same tofacilitate starting thereof. When the engine has run for the desiredperiod and the cylinders have been brought to proper workingtemperatures, the head 17 may be moved slightly upwardly by the toe ofthe foot of the operator, thus disengaging the notched portion 16 fromthe guide cap 18 and permitting the eXpansible spring 19 to return theplunger rod to its normal or closed position, thus discontinuing thepassage of fuel from the fuel tank to the engine cylinders. When the caris cranked from the front thereof, the valve may be operated by the wire20. By pullin the wire forwardly the lever 10 will be roc ed in adirection to open the valve and also will move the plunger rod 15inwardly whereupon the notched portion 16 will engage with the adjacentportion of the guide cap 18, thus maintaining the valve in its openposition until the engine has run for a suiicient time in order that thecylinders of the same may be brought to the proper temperatures. At thistime, the plunger rod 15 may be disengaged by moving the head 17slightly upwardly to dis- Iii engage the notched portion 16 from the Yguide cap 18.

Manifestly, the construction shown is capable of considerablemodification and such modification as is within the scope of my claim, Iconsider within the spirit of my invention.
